ASP.NET Core如何在发行版中删除特定的CSS和JavaScript文件

我的问题是，当我使网站正常运行时，但当我将其放到服务器上时，会显示以下CSS和JS块：

<link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/css/bootstrap.min.css" />

我确实检查了布局文件，并且它分别具有css和js的Develepment，Staging和Production的环境exclude标签。

那么为什么发布网站时会显示排除的代码？

任何帮助将不胜感激

1 个答案:

答案 0 :(得分：0)

您的最终标记似乎工作正常，因此对于您的确切问题我有些困惑。您已经定义了两个环境条件，但是它们看起来都具有完全相同的标记，因此将在开发和生产/阶段上呈现相同的标记，这没有任何意义。

首先，您要定义将在开发中显示的内容，这应该是没有降级或版本控制的本地未缩小版本：

<environment include="Development">
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css" />
    <link rel="stylesheet" href="~/css/site.css" />
    <link rel="stylesheet" href="~/lib/kendo-ui/styles/kendo.common-nova.css" />
    <link rel="stylesheet" href="~/lib/kendo-ui/styles/kendo.nova.css" />
</environment>

然后，您定义可以使用CDN，回退，缩小和版本控制的生产标记。

<environment exclude="Development">
    <link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/css/bootstrap.min.css"
          asp-fallback-href="~/lib/bootstrap/dist/css/bootstrap.min.css"
          asp-fallback-test-class="sr-only" asp-fallback-test-property="position" asp-fallback-test-value="absolute" />
    <link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" />
    <link rel="stylesheet"
          href="https://kendo.cdn.telerik.com/2017.2.621/styles/kendo.common-nova.min.css"
          asp-fallback-href="~/lib/kendo-ui/styles/kendo.common-nova.min.css"
          asp-fallback-test-class="k-common-test-class"
          asp-fallback-test-property="opacity" asp-fallback-test-value="0" />
    <link rel="stylesheet"
          href="https://kendo.cdn.telerik.com/2017.2.621/styles/kendo.nova.min.css"
          asp-fallback-href="~/lib/kendo-ui/styles/kendo.nova.min.css"
          asp-fallback-test-class="k-theme-test-class"
          asp-fallback-test-property="opacity" asp-fallback-test-value="0" />
</environment>

鉴于已在目标系统上正确设置了环境变量，第一个块将在开发中可用，第二个块将在登台/生产中可用。
